What do you think the cost of maintenance will be a year?
What do I need to have done to this thing, or what should I make sure HAS BEEN done? Timing belt/water pump? Or what repairs/maintenance should I be looking for?

I love the car, but I hear bad things about maintenance costs. Hope you guys can confirm/disprove this.

What is the cost of those minor things. Tires, brakes, etc.?
Plus... Whats involved? Are BMW's any more difficult to work on than other cars?
